如何计算Electric Vehicle T C O
learn.whatIsHeading
Electric vehicle total cost of ownership compares purchase price, fuel cost (electricity), maintenance, and incentives over ownership lifetime.
分步指南
- 1Calculate: TCO = purchase price + fuel cost - incentives + maintenance over vehicle life
- 2Electricity: ~$0.03-0.05 per km, gas: ~$0.08-0.12 per km
- 3Break-even often 5-7 years, then EV cheaper lifetime
例题解析
输入
EV $35,000, gas car $25,000, 150,000 km over 10 years, EV tax credit $7,500
结果
EV TCO $28,500 vs gas $39,000 lifetime cost
EV cheaper overall
常见错误注意事项
- ✕Only comparing purchase price without including fuel and maintenance
- ✕Assuming old battery replacement costs (now much cheaper)
常见问题
Do battery replacements make EVs expensive to own?
Modern batteries last 10-20 years; rarely replaced in vehicle life. Costs decreasing rapidly.
How does electricity source affect EV economics?
Renewable grid electricity dramatically improves EV advantage. Even coal-powered EV cheaper to operate.
